Description

The smoke purifying lighting device that is used for laser operating apparatus

A kind of smoke purifying lighting device that is used for laser operating apparatus relates to the improvement of laser operating apparatus.

In laser surgery,, when lesion tissue is subjected to the calcination vaporization to become smoke-like gas, can decomposes and discharge carbon monoxide, carbon dioxide, harmful gass such as hydrogen sulfide as eliminating nevus cell nevus, eyelid squamous cell carcinoma, skin tumour, clavus, hemorrhoid etc.Some focus vaporization smog is really understood virus spread, and all focus vaporization smog all have the abnormal flavour of coking corpse, so focus smog has four big harms at least: 1, focus vaporization smog makes operation visibility feculence, hinder the sight line of surgical staff, directly the process and the quality of influence operation to intracavity operation; 2, abnormal flavour makes the operation technique personnel psychology be subjected to very big threat, remote-effects the operation quality; 3, the not treated discharge of harmful focus vaporization smog, the physical and mental health and the contaminated environment that endanger on-the-spot medical worker.For this reason, use the operator of laser scalpel, urgent hope has a way of properly settling.

Up to the present, there is no reported in literature both at home and abroad, also not seeing has practical system properly to address the above problem.Domestic have indivedual medical institutions once to do effort in this regard, their way is to adopt the petticoat pipe of similar smoke exhaust ventilator formula substantially, with air exhauster focus is vaporized smog emission in outdoor air, though this easy device can partly be improved the environment of indoor operation, but still have following problem: 1, the discharging of focus vaporization fume extraction is incomplete, and abnormal flavour still exists; 2, external equipment is bulky, heavy, and it is very inconvenient to use, and also needs the special messenger to hold suction pipe and cooperates; 3, exhaust suction tube can't enter the operation intracavity, and intracavity smog still can not in time be discharged when full, and the smog of discharging easily infects the crowd without effective purified treatment contaminated environment still.

Purpose of the present invention, it is little to be to produce a kind of volume, the equipment that can be fitted together with former laser operating apparatus, both can collect and purify the focus vaporization smog that produces in the operation effectively, can make things convenient for medical worker's operation again, guarantee the carrying out of intracavity outer operation, reduce infection operator, and have the device with the synchronous tracking illumination of laser operating apparatus, be particularly useful for intracavity operation.

Enforcement of the present invention is such, opens an inclined hole that is about 15 ° of angles on outlet tube chuck 9 tube walls of laser operating apparatus, is connected to smog collecting pipe 6 on this inclined hole, and flexible pipe 12 joins with depurator 13 through bleeding.On the lower edge tube wall of the outlet tube chuck 9 of laser operating apparatus and lens barrel 1 junction, have the fine and closely woven passage 4 of a circle, a funnel-form guard shield 5 is housed below passage 4, on laser probe 2, be with a transparent casing 7 that matches with former cutter head; Depurator 13 is made up of one-level or the filter more than the one-level, in order to guarantee clean-up effect, generally all adopts the above polishing filter of secondary.At the first order filter 14 that joins with the flexible pipe 12 of bleeding in a tubular form, employing can make things convenient for the filter tube of once changing, do casting resin by the strong adsorbent of adsorptivity in the pipe, it can be the felts material, after first order filter 14, add second level filter tank 15 through the flexible pipe 12 of bleeding, this filter tank is done the Filtration Adsorption agent with activated carbon, and operator are dismantled freely, so that the periodic replacement filter medium.Be connected to the high-speed electric expreess locomotive 16 of a belt switch and adjustable speed at the end of filter tank 15, make focus vaporization smoke collector form negative pressuren zone, the smog of when being convenient to perform the operation focus being vaporized is extracted out and is filtered.In order to improve the laser surgery quality, improve the visibility in the operation process, the visibility of intracavity operation particularly, adopt in the present invention and can transmit cold light by arbitrarily crooked optical fibers, by the low pressure iodine-tungsten lamp as cold light source, send into optical fibers 8 behind optical focus, this optical fibers 8 is through the outlet tube chuck 9 of the laser operating apparatus outer wall attached to laser surgery cutter head 2.

Below in conjunction with accompanying drawing in detail principle of the present invention and using method are described in detail.

Figure one is a device sketch map of the present invention.

Figure two is the cutaway views that the cold light fibre-optic bundle are attached to the outer side of laser probe;

Figure three is the outer wall cutaway views that the cold light optical fibers are evenly distributed on laser outlet tube chuck and laser surgery cutter head.

Figure four is part sketch maps of secondary purification exhaust device.

As shown in the figure, before using device of the present invention to perform an operation, earlier the main power 17 of control chamber is opened, open or close cold light source switch 18 then as required, step on foot-operated negative pressure switch 19 with the foot pump, connect the power supply of high-speed electric expreess locomotive 16 by the operation doctor, make and form negative pressure in the laser surgery cutter head 2, after laser scalpel being aimed at the focus of required operation, the reuse heel is stepped on the power supply of laser scalpel, sends laser beam and carries out calcination.Because the vaporization smog that laser calcination focus produces is High Temperature High Pressure, in case form, promptly being started the formed high negative pressure in back by high-speed electric expreess locomotive 16 is pumped in the depurator 13, influence suction effect in order to prevent that air beyond the laser probe from also pouring in from the wedge-like indentation, there of cutter head 2, therefore outside cutter head, put a transparent hose 7, observation when neither influence is performed the operation can keep the negative pressure draft again.Because the gas humidity after the focus vaporization is quite high, except that major part can by high-speed electric expreess locomotive 16 formed negative pressure is disposable siphon away, still have the gas of minute quantity to rise on the germainium lens sheet 3 along the laser output channel, make eyeglass 3 be subjected to easily pollute corroding and damaging, for this reason, on the joint bottom tube wall of lens barrel 1 and the outlet tube chuck 9 of laser operating apparatus, be drilled with the fine and closely woven through hole 4 of a circle.Because in the pipe is negative pressure, the outer clean air of pipe is sucked by these apertures, forms downward air curtain one, has protected minute surface 3.In order to strengthen the air that presses down, also set up a funnel-form guard shield 5 in the bottom of gas curtain, both can allow laser beam pass through, increase the flow velocity of clean air in the passage 4 again, force the focus vaporization smog of rising to form backflow, form turbulent flow in guard shield 5 bottoms, stoped the rising of focus smog effectively, force its inclined hole smog collecting pipe 6 to send into the depurator 13 from tube wall.

When the vaporization smog of focus enters the first order filter 14 of depurator 13 from pump-line 12, owing to be to adopt the filter tube that can make things convenient for disposable replacing, the casing pack thing is the felts material, the harmful substance of major part can be adsorbed to fall, processing filters 14 is changed in the back of should at every turn performing the operation like this.The remaining gas that has a small amount of pathogenic virus continues to enter second level filter tank 15, can adopt active carbon to make adsorbing medium in groove, and the harmful substance that still exists after like this first order filter 14 being filtered continues can be clean by activated carbon adsorption.This second filter 15 is demountable cell bodies, and the activated carbon of the inside can regularly replace (replacing of needn't at every turn performing the operation).

Generally speaking, can reach 99.8%, we can say nontoxic no stink through this twice basic purifying rate of filtering gas.Not only ensure staff's on the scene physical and mental health, guaranteed the operation quality, and purified environment.

Because the cold light tracking illumination device among the present invention provides light source after with the line focus of low pressure iodine-tungsten lamp, optical fibers 8 can be arbitrarily crooked, both can send synchronous tracking cold light with laser operating apparatus easily, can avoid the scorching hot effect of the on-the-spot illumination of electric filament lamp again, particularly intracavity operation is very suitable to laser surgery.Optical fibers 8 through laser scalpel chuck 9 attached to the laser scalpel outer wall, also can evenly braiding around laser probe 9, make things convenient for using and increasing the service life of medical worker.

Device of the present invention can be combined in one with laser operating apparatus, also can be used in combination with calcination operating theater instruments such as high frequency electric knife, high frequency electroacupunctures.

Adopted the present invention, can improve the quality of laser surgery, expanded the scope of laser surgery, thoroughly having eliminated due to illness, kitchen range vaporization smog has improved surgical environments to the secondary pollution of human body.Device of the present invention not only goes for laser operating apparatus, can also be applicable to that high frequency electric knife, high frequency electroacupuncture etc. burn operating theater instruments, have the prospect of using widely.
